Phishing is an attack in which an attacker (in this case, a phisher) sets up a spoofed web site that looks similar to a legitimate web site The attacker then attempts to lure victims to the spoofed web site and enter their login credentials, such as their usernames and passwords In a phishing attack, attackers typically lure users to the spoofed web site by sending them e-mails suggesting that there is some problem with their account, and that the user should click a link within the e-mail to verify their account information The link included in the e-mail, of course, is to the attacker s web site, not the legitimate site When unsuspecting users click the link, they arrive at the spoofed site and enter their login credentials.

The details of the CityRepository can be found in the code samples provided with the book. For now, we ll focus on the new Find(string q) action. Because this is a standard action, we can navigate to it in our browser and test it out. Figure 27.3 shows a quick test.

GtkCellRendererAccel provides the following four properties that can be accessed with g_object_get(): accel-key: The key value that corresponds to the accelerator. A full list of key values can be found in <gdk/gdkkeysyms.h>. accel-mode: A GtkCellRendererAccelMode value GTK_CELL_RENDERER_ACCEL_MODE_GTK or GTK_CELL_RENDERER_ACCEL_MODE_OTHER. This defines how the accelerators are rendered within the cell. You should usually use GTK+ s version of rendering. accel-mods: An accelerator modifier of the type GdkModifierType. This allows you to detect Shift, Ctrl, Alt, and other masking keys. keycode: The hardware keycode of the accelerator, which is not usually used. This is only necessary if you do not define a key value.

The site simply logs the credentials, and either reports an error to the user or redirects the user to the legitimate site (or both) The attacker later uses the logged credentials to log into the user s account and transfer money from the user s account to their own Why do users fall for clicking such links in e-mails sent by phishers Phishers use various techniques to hide the fact that the link is to their illegitimate, spoofed site Following is an example First, in HTML documents, a link is constructed as follows: <A HREF='http://wwwdestination-sitecom/'> Click here </A> When the e-mail is rendered by a browser, the link will look like this: Click here, and the destination address will not be apparent to an unsuspecting user An attacker can use code such as the following in an HTML e-mail sent to the victim: <A HREF=http://wwwevil-sitecom/> http://www.
